OIL-BURNER.

Application filed August 2, 1919.

To all whom t may concern.'

Be it known that Josiirir l). Sciiiiiiinn, a citizen of the UnitedStates, residing at Mayfield, in the county of Santa Clara and State ofCalifornia,ihas invented new and useful Improvements in Oil-Burners, ofwhich the following is a specification.

The object of the invention is to provide an improved form ofhydrocarbon burner adapted for use in cook stoves and the like. To thisend the invention comprises an improved generator in the form of atubular ring in which there is inclosed a plurality of balls over whichthe fuel must pass to reach the jet. The burner is designed to hold thering-like generator in a vertical position and fuel is admitted to thelatter at the upper end thereof, the jet being carried at the lower endof the ring and positioned on the inner periphery so as to direct itsllame against a spreader.

A further object .of the invention is to provide a device of this kindwhich is simple in construction, durable and effective in operation andinexpensive to manufacture.

Other and further objects appear in the following description whereinthe invention is set forth in detail.

To the exact construction in which the invention is set forth, it is notto be restricted. The right is reserved to make such changes oralterations as the actual reduction to practice may suggest, in so faras such changes or alterations are compatible in spirit with the annexedclaims.

In the accompanying drawings:

Figure 1 is a vertical sectional view through the improved device.

Fig. 2 is a section on the line 2 2 of Fig. 1.

Fig. 3 is a section on the line 3-3' of Fig. 1.

Fig. 4 is a central vertical sectional view through the jet.

Referring to the drawings, the invention comprises a generator 1 whichis in the form of a tubular ring provided at a point on its outerperiphery with an internally threaded inlet portion 2 adapted to receivea reducing coupling 3 with which a nipple elbow 4 engages, a supply pipe5 being con nected with this nipple elbow and the pipe connecting with aneedle valve 6 to which the fuel supply pipe 7 is led. The generator ismounted in the upright position shown in Fig. 1 with the inlet 2 at thetop`and this Specification of Letters Patent.

generator carries on its interior a series of balls 8. The ring 1 at thebottom is formed with an externally threaded nipple 9 to provide for itsattachment to the generating pan 10 which is circular in plan and whichat its center is provided with an interiiallv threaded hub portion 11 inwhich the nipple 9 engages. The nipple 9 is internallv threaded so thata drain `pipe 12 mav be attached thereto; this drain pipebeinguconnected with a valve 13 vwhich. when open will permit thedraining of sediment or foreign matter from the device and which whenclosed, will insure the direction of the fuel into the jet 14 which isexternally threaded and secured into an appropriate hole formed in thering or generator 1 on the inner periphery of the latter and inalineinent with the nipple 9. The jet 14 carries a plate 15 whichseparates the adjacent balls at the lower end of the ring and spacesthese balls far enough apart to preclude their free entrance of fuelinto the jet.

In orderl that the fuel may readily pass from the pipe 5 into the ringor generator 1. a coil spring 16 is disposed in the inlet por-l tion 2beneath the coupling 3 and bears on the balls adjacent the inlet tomaintain the two on the opposite sides of thev center of the inletspaced so that they may not obstruct the passage of fuel from the pipe 5into the ring 1.

The ring 1 on the inner periphery and directly below the inlet 2 isformed with a flange 17, to which a flame spreader 18 is attached bymeans of appropriate bolts 19.

The device is designed for the burning of kerosene and for distilled andstove oil. If the former is used the opening in the jet 14 is the sizeof a 68 drill. For distilled and stove oil the opening in the jet isabout the size of a 50 drill. The device is designed for mounting in acoal stove, the generating pan serving as a base and being supported onthe grate. The pipe 12, if desired, may be led to the exterior of thestove through a suitable hole drilled therein. The needle valve 6 ispositioned outside of the stove but it is connected with the burnerthrough the pipe 5 which passes through, a suitable hole drilled in theside of the stove. 0n the opening of the needle valve, a sufficientquantity of oil will be permitted to pass through the generator 1 andout through the j et to enter the generating pan 10. Sufficient oilhaving been allowed to enter the said pan, the

needle in the valve is closed and the oil in' the pan ignited. By thetime this oil has been burned oil, its combustion Will have heated thering l to a suiicient temperature to cause it to vaporize any oil thatmay thereafter be permitted to enter. T he opening of the needle valveWill then allow oil to enter the ring l and this triclles over the balls8, the heat to Which the ring has been raised generating gas which,entering the jet le., will be ignited therein and How therefrom in a dane directed against a spreader 1.8 which spreads the 'flame and thuskeeps the generator ring l hot as Well as generating an intense heat inthe stove,

YEhe. fuel purchased from the open market is not al vays clean5 itcontaining more or less sediment., rl`he draining feature ot the deviceeliminates all trouble from that source since it permits the draining oi`the burner after use and when the needle valve 6 is closed.

The burners may be built singly or in units containing tivo or moreburners depending on the sise ot the stove in which the device is beused.

rElie invention having been described, what is claimed as new and usefulis:

il hydrocarbon burner consisting of' a vertically disposed tubularring-like generator. a supply pipe connecting with the generator on top,jet disposed on the inner periphery of the generator on the bottom, aplurality .of balls housed Within the generator and over which fuel mustpass to reach the yet, and a spacer connected with the jet and standingbetween adjacent balls at the bottom ot the generator to provide for thefreedom of flow of fuel from the generator into the jet.

2. A hydrocarbon burner consisting of a vertically disposed tubularring-like generator, a supply pipe connecting With the generator on top,a jet disposed on the inner periphery ot the generator on the bottoni, aplurality oi balls housed Within the generator and over which fuel mustpass to reach the jet, and a generating pan serving jointly as a basefor the burner and a fuel holding means to start the initial generationof gas.
